T0 all whom z't may concern.'

Be it known that I, SAMUEL E. CAnLiN, a citizen of-fthc United States, residin at Chicago, Vjn the county f Cook and i useful Improvements in Calculating-Ma chineS, of which the following is a specification.

This invention relates to calculating inachines, and articularly to such as are employed in tagulating, and adding` the totals of'tabulated figures or columns.

A ymachine constructed accordiiinr to this invention enables a plurality of columns to b e footed up on the tabulated sheet, and the numbers are added, in the totalizers'or registers, which correspond to tliesaid col- V umns. As the numbers are added they are writteniipon the tabulated sheet.' Although l under normal conditions a column writtenv at the left of the sheet willhave its numbers added on 'a corresponding totalizer at the.

y left 'ofthe machine, the arrangement is such aSto'permit the writing of a column at any point on the sheet, and the simultaneous addin of the .figures of this column in any one o the totalizers. To effect this freedom of control is one of the objects of the invention.

" Another. object is toconstruct the calcu-` Iating mechanism so as t enable it to be readilyconnected to :in oi'dinary typewriter. When' thecalculating machine is so conthe typewriter, connections are made to the typewriter keys, so that when the number keys of 'the calculating machine are' depressed, the corresponding key of the type- ,v i writer will be depressed, and that number 40 printed 'upon the machine.'

In theform of the invention illustrated, thilicalculutiiig mechanism includes a plurality lifi`totitlizers or registers', which `are viiiid'a'iiged endto end in longitudinal alineint, and iicomputing carriage is provided onfwliicli there is mounted a plurality of master wheels, which are normally disposed near biitfo'iit' of ali'neinent with the wheels of the totalizerls. douncction is made from the typewriter carriage to this computing"| cu,'rriage,so that when the typewriter cnrringe' is advanced through tht` operation of its escapemeiit. the coii'ipiitiiig carriage `will be i 'Coriespoi'id in gly a d iaiiced.

ate of Illinois, haveV invented certain new and In their normal positions, the master wheels :fre not active to operate the tota-lizcrs, but any master wheel may be put into active connection with its totalizcr by depressing the proper key of the calculating machine. This is done befoie the number is added, and selects or determines the total izer upon which this particular column will be added. The computing carriage advances along the active totalizer, and comes successively into connection with the wheels of different denominations. And the number keys of the calculating machine control the mecha ism which actuates the master wheel, so as to gi'vc it the proper amountbf rotation. This master wheel advances automatically along the totalizer, and upon the dpression of any ykey suoli as the eight key of the calculating machine, the'master wheel is given the proper rotation to correspond. The master Wheels arc mounted upon a rocking `frame, and inone of its positions this frame holds the master wheel removed from the wheels of the totalizers, and in this position, they are advanced from the wheels of one denomination to the next. As each digit is added, this automatic advance takes place,and the rocking frame then rocks toward the totalizer, so as to bring the active master wheel into mesh with the driven gear of the totalizer. The degree of rotation which is transmitted by theactive master wheel`is" determined by the depression of the numberkeys of the calculating lmachine, and the motion is produced by means of thc motor which makes one complete revolutionmay be madeactive by the depression of its correspondinor number key, the amount of rotation of tie master wheel is determined.

An arrangement is provided whereby, when the selecting key of the calculating machine has been depressed it will be automatically locked against return, and in addition to this, all oftheother selecting keys which control the actuation of the totalizers are automatically locked simultaneously.

Referring more particularly to the drawings, and in the present cxempliiicatiou of the invr-intion, the numeral 35 designates a supporting basc arranged at the forward edge oil which arr .suitable uprights3G,which are spaced from cach other. lVith its @nds pivotallv mounted in these uprights is a support or rail 3T. which is preferably rertangular in crosssection, and this support is adapted to hohl the lotalizers or registers `designatcd generally bv the reference nu- -meral 38.

The. frame of the totalizers is provided with a base comprising spaced jaw members 3L), 40, foi-ming sockets through which the support 37 extends whereby the totalizers will be detachably secured thereto. lVhen the support 37 is in the position shown in l `igs. 1 and 8. the totalizers will be held in position for use. lVlien it is de-` sii-ed to remove one or more of the totalizers without dismantling the entire mechanism, the support 37 may be rotated about its end pivots, after which the totalizers may be readily detached. In order to hold the support. in either of its adjusted positions, one of the ends thereof which iS reduced to form the pivot or trunnion is provided with a collar 41 having notches 42,' 43, and a retaining dogr pawl 44 (see Fig. 19) is pivotally mounted upon the adjacent support 3G, and held by a spring 45 in either of said notches.

Mounted upon the base 35 and in the rear of the uprights 36 and the totalizers 38 is a computing carriage 46 comprising a base and uprights 47, the base of the carriage moving between guides 48 and the edges of the guides and the carriage are provided with race ways for the antifriction balls 49, so that the carriage will. reciprocate readilv within its guide. The carriage is of a length somewhat shorter than the width of the base 35, as shown more clearly in Figs. 10 and 11, and journaled in theuprights -His a shaft 50 which is gf-a lengthsubstantially equal to the length of the carriage as shown more clearly in Figs. 10, 11 and 12;

A shaft 51 is arranged above the shaft 50 which4 will no'w be described.

and is journaled in suitable supports 52, in the form of rocking plates. One of these supports is arranged adjacent each end of the shaft and both these supports are pivotally mounted on the shaft 50 (see Figs. 10, 11, 12 and 17). These supports are connected to move in unison in any esired or suitable manner, preferably by means of a bar or connecting member 53. In thispway they form a rockmg frame,` The shaft 451 is provided with gears 54 locatekladjacent the extremities thereof and these' gears 54 mesh with gears 55 on the shaft 50, so thatwhen the shaft 50 is rotated, motion will be imparted to the shaft 51. Mounted upon and for rotation with the shaft 5l are a series of master wheels or ears 56, and these gears are also mounted or adjustmen lon tudinally with respect-to the sha t.4 ne of these gears 56, is provided for each of the totalizers 38, and the shaft 51 is so mounted with respect to the totalzers that the gears-56 thereon when adjusted into positions for operation, will engage and mesh with the respective gears 5? of the respective totalizers (see Fig; 8). The gears 56 are normally heldin an inoperative position with relation lto the respective gears 57 so that when an one or more of the totalizer's, is rendere inactive, theA master gears 56 which control the 'remaining tptalizers will not operate their respective inactive totalizers 'during the operation of the active totalizers, that is to say, when itis desilied .to register on any one or more of the totalizersj38, the actuating gear 5,6 of that to' talizer must be first set by the selective mechanism, and this operationmay be accomplished without affecting the other gears 56. In order to hold the gears '56 normally vin an inactive position, suitable mechanism is provided for this purpose Looselymounted upon the shaft ,50" are a plurality of sleeves 58 which arel provided with circumferential ribs or projections 59,

and extending upwardly from each' of these l 'sleeves 58 are arms60 which al" spaced from eachother and are,provi de'd: with U-shaped yokes 61 at their 'upper extremities, and

, which yokes 61Ustand astride of the shaft 51.

One of the arms 60 is located on each side of each of-the gears 56, so that when' the sleeve 58 is moved. longitudinally on the shaft 50, the re ective gear 56 will be correspondn'gly shiftedl to place the Vgear so that it will mesh with one of the gears of the respective totali'zers when the supports `52fare shifted. In order tjlock the number wheels of ythe totalizers against overthrow,

suitable `locln'ng and tens carrying members '62 are yprovided (see Fig."15) which are provided with teeth 63, andY these "members are loosely `mounted for oscillatory moveV ment on the shaft 51. The locking and tenscarrying members are spaced from each other a 'distance equal to the 'space between the gears 57 of the totalizer so that when the' gear 56 engages one of the gears 57, the teeth 63 of the locking member 62 will engage the next adjacent` gear 57 when the carriage 46 has advanced far enough. These locking.' members 62 are held in their adjusted positions by means of a ratchet member 64, one of which is provided for each of the members 62, and these ratchets 64 are provided with a plurality of vteeth 65 be tween which a dog 66 is adapted to project, and this dog 66 is provided with a yielding member 67 for controlling the same. The dogs 66.are preferably mounted upon a support 68 which latter is mounted in the supports 52;

The selective mechanism for shifting the gears 56 into active positions 'comprises stems 69 which are arranged in upright po sitions and are supported by means `of a guide 70, which guide preferably forms a continuation of theuprights 47, and.

through it the stems loosely pass. A collar or shoulder 71 is provided adjacent the lower extremity of each of the members 69, and a' spring spective` col ar and the carriage 46, to return thestern when depressed. The ex 'tremity of the stem or member is adapted to be projected into an openin 473 in' the car-l jection 77 in 'the notch or bifurcation. Each' of the .sleeves 75 is providedV with a seg- 'Inent 78 (shown -more `clearly in Figs. 8, 10 and 11) and the teeth of thissegment'cooperate with the projections or shoulder-S59 onthe sleeves 58 so thatwhen the sleeve 75 isrotated about the member 69as anA axis, thesegment 78,'of the sleeve will shift the gear, 56 longitudinally on the shaft 51. .Tlie stems 69 are ada ted to be depressed against the tension of t e spring 72 to unseat the pin or projection 77 from the notch 76 inv f' any' desired or suitable manner, and in order to permit the carriage 46 to reciprocate, and

at the same time toldepress the rods or mem-,

bers 69 when the carrie e 46 Vis in any posibe described.

of which project laterally from the member. A guide 81 is held in position by means of uprights 82 which are secured to the base 35, and rectangular frames 83 are provided as indicated in Fig. 12;'and the side bars 84 of these frames pass through suitable guide bearin 85 in the guide 81. The lower extremities of the side arms are connected by cross members 8G, and these cross members extend into the bifurcated portions 80 ofthe member 69 so that the carriage 40 may maintain its connection with the stems during its travel, and when so moved, the members 09 will slide with relation to the members 8G of the respective frames 83. Buttons 87 are provided, one for each of the frames 83, so that by'depressing the buttons any one of the totalizer mechanisms 38 may be rendered active at the will of the operator. Any suitable means may be provided for automatically rotating the `sleeves 75 to shift the gears 50 on the shaft 51 when the Sleeves are released or unlocked, that is, when thepin or projection 77 is unseated from the notch 70. In order to accomplish this result, each of the sleeves 75 is provided with a laterally projecting pin or arm 88, and a spring 89 is secured by one extremity to the pin or projection and is anchored by its other extremity to a fixed support, preferbly av projection 90 extendinglr from the support 74; The springs are so arranged that, when the gears 56 are moved dut of active positions, that is, are moved into positions suoli that they will not cngage one of the gears 57 of the totalizers, the springs will be placed under tension so that the moment the sleeves 75 are released, the springs will exert their tension upon the Sleeves 75 to rtate them.

Any suitable means may be provided for rotating the sleeves 75 in the opposite direction, so as jto hold and'lock the master gears 56. in inoperative positions. For this purpose there may be provided a bar 91 which' extends transversely with respect to the arms 88 and parallel with the shaft 50. This bar 91 is preferably provided with notches 92 (see Fig. 12) into which the arms 88 extend, and `is supported preferably by means of arms 93 which latter' are secured to rock shafts 94 mounted in suitable bcarings 95. y In order to impart `axial rotation to the sleeves 75 by the bar or member 91, it is necessaryto rock the shaft 94, and consequently the arms 93 against the tension of a spring 96, one end of which is secured to the bar 91 and the other end of which is anchored to a suitable support. This' spring 96 tends to move the bar 91 in one direction, and bars or members 97 similar to the members 69 are connected by one extremity to arms 98 secured to the shafts 91 (see Figs. 8, 10 and 11). The upper extremities of these bars 97 pass through the guide 70 in a similar manner and are provided with bifurcated heads 98 having spaced rearwardly projecting forks 99 between which a bar 100 extends (see Figs. and 8), and a releasing key or bar 101 is secured to this bar 100, so that. when the bar or key is depressed, the shaft 91 will be rocked to move the bar 91 and thereby rotate the sleeves 75; this positions the notches with respect to the pins or projections 77 on the stems 09 so that the springs 72 will move the stems (59 longitudinally to seat the pins 77i'in the notches 70. rThis bar 101 may be located in any convenient position, but is preferabl located in advance of the frames 83 whicli are controlled by the keys 87, as shown more clearly in Figs. 3 and 8.

In order to permit thc active master gear 50 to move 'from one to the next of the gears 57 ot' the respective totalizcrs 38 as the earriage advances, it is necessary to move the gears 50 away from the totalizers during the advancing movement of the carriage. If this were not done the sides of the gears might strike together, and prevent their meshing. After the carriagel 4,0 has ads vanced, the gears 56 are then moved laterally back toward the totalizers so that they may engage or mesh with the gears 57 of the next denomination. In order to accomplish this, the rocking frame which comprises the supports 52 and the connecting member 53 is swung about its point of pivotal support on the shaft 50 by mechanism which will now be described, and which l'mechanism will not interfere with the reciprocation .of the carriage 40 and the gears 50. Pivotally supported, preferably by the bar or connecting ntember 53, and intermediately of their ends, are a plurality of arms 102, one of which arms is provided for each of the locking members 02 of the number wheels of the totalizers. These arms are prcferably eight in numberone for each of the number wheels with the exception of the number bearing member of the lowest denomination. These arms 102 are connected with thc respective locking members 02 by means of a loose connection, preferably in the form of a pin, and slot connection 103, 104, (Fig. 17,) so that theloeking members 02 will be permittedto have only a limited oscillatory movement about the shaft 51. The free extremity of the arms 102 is enlarged as at 105, and is provided with an aperture or opening 100, the sides 107 of which converge from a point adjacent the point of pivotal support to the end 108. The wall of the aperture 100 opposite to the reduced portion 108 is formed with a cam surface 109 for a purpose to be set forth. Journaled in suitable supports 110 mounted upon the base 35 is a rock shaft 111 which is of a length substantially equal to the width of the machine. This shaft 111 is preferably located in a' plane below the shaft 50, secured to this shaft 111, preferably adjacent the extremities thereof are arms 112 which are connected at their free extremities by means of a bar, or cross member 113 which extends through the apertures 106. in the ends 105 of the arms or members 102. This connecting bar 113 is of a diameter somewhat less than the diameter of the aperture 106, so that the arms 112 and the member 113 may move independently for a limited distance with respect to the arms 102. The arms may be spaced from each other in any suitable manner, preferably by means of spacing collars or washers 114.

When the shaft 111 is rocked in a manner which will be hereinafter set forth, and assuming the cross lbar or member 113 to be in the position shown in Fig. 17, the member 113 will be moved toward the end 108 of the aperture 106 in the extremities 1051 and will be directed into the end by the inclined sides 107. This movementof the member 113 will rock the arms 102 about their p ivots and consequently the locking members 62, so as to return them to normal position when the gears 56 are moved out of engagement with the respective gears 57 of the totalizers. In this position the carriage 46, together-With the supported mechanism may be advanced or retracted. At the end of the step of advancement the shaft .111 will be rocked in a manner tobe set forth, so as to move the member 113 against the cam face 109 of the arms 102, and this movement will swing the rocking frame (coniprisingr the'supports 52 and the connecting bar or member 53) to place the active gear 56, which has been slid Vinto operativeealinement, actually in mesh with the corresponding 'gear 57 of the totalizer. Should the gears 56 be in such aposition as to mesh with any of the gears 57 of the respective totalizers other than the gear 57 which comprises the number wheel of the highest denominatiomone or more of the locking members 62 will also be in mesh with the respective gears 57, owing to the fact that the cal riage 46 supporting this mechanism has been advanced. In this position it will be apparent that when the number is carried from a number 'wheel of the totalizer to the neigt adjacent number wheel of a higher denomination by means of the carrying mechanism which will be presentlydescribed, the number wheel of the higherdenomination will cause its gear 57 to be rotated during the. carrying movement, 'and this rotation of the gear will correspondingly rock Vthe locking member 62 about the shaft 51.

During this operation, the locking member' 62 will restrain br lock the number Wheel against overthrow. In order to permit this operation, the pin and slot connection 103, 101 between the locking members andthe arms 102 is provided, and this loose con-` nection, together with the cam face.109 which coperzrites with the bar 113 on the arms 112 'l1 permit the locking member to have onry a imited degree of movement in either direction, and when so adjusted, the locking member will be held in its -adjusted position by the dog or pawl 66 during the time that the lockin member is in engagement with the gear 5 After the calculation or carrying operation, the shaft 111 will be rocked and the member 113 will be moved out of engagement with the cam 109 so as to rock the arms 102 about their pivots in the manner already set forth, and this rocking movement of the arms will )nove the locking members 62 in the opposite direction to true the locking members, and during this movement the dogs 66 will yield so that they will enter another space between thevprojections on the elements 64. The advancing movement'of the carriage t 46, together with'the mechanisms supported thereby, is controlled by the movement of the typewriter carriage, designated generally by the reference numeral 115 of thel typewriter 116 (shown in F igs. 1 and 4'). and which carriage is intermittently adyanced in the ordinary and well known manner by the manipulation of the spacing' liey of the typewriter. In order to accomplish this.,.

result, intermediate connectin lmechanisms between the typewriter carriage` and the carriage 46are provided, and these connec# tions preferably comprise a rack 117, which is secured to and supported for movement with the carriage 46, as shown more clearly in Figs. 1, 8, 10 and 11. An arm 118 is pivotally supported intermediate its ends, as at 119, and is provided with a toothed segment 120 on one end thereof, and which segment meshes with the rack 117 on the carriage 46, so that when the arm 118 is oscillated about its point of pivotal support 119, the 'carriage 46 will be correspondingly reciproated. l The other end of the armr118 ,n

is also provided with a segment 121 which meshes with a gear 122, which latter is con -nected with an upright shaft 123 at the rear of the typewriter mounted in suitable bearings 124. This shaft 123 is connected at its upper extremity with a geary 125 which meshes with a rack 126 supported bythe typewriter carriage, so that when the type-A writer carriage is spaced in the ordinary and well knownmanner, motion will be imparted Vto the shaft Y123 ,through the medium of the rack 126 and gear 125, and which motion will in turn be imparted to the arm 118 through'the medium of the gear 122 onthe shaft and the segment 121 on the arm 118. 'y

In order that the shaft 50 may be adjusted longitudinally at the same time that the carriage 46 is' adjusted, and also to .be

.support 125).

`and 17), and meshing with this drum or cylinder 127 is a gear 130, which hitter is secured to and for rot-ation with the shaft 50. The Supports for this drum are stationary and the drum is fixed, so that when the carriage 4G is reciprocated, the gear 13() on the shaft 50 will remain in mesh with the teeth on the drum and will be reciprocated longitudinally with respect to the drum, the drum being of a length to permit the full reciprocation of the carriage. Any suitable means may be provided for imparting motion to the drum, and for this purpose there provided a shaft 131 which extends transversely across the machine parallel with the shaft ,50, and is journaled in suitable supports 132, 133, 129 Figs. 10, 11 and 17). One extremity of this shaft 131 projects beyond the support 129 and secured thereto and for rotation therewith are gears 134, 135, which gears are prefer ably spaced from each other by means of a spacing collar 13G, and one'of these gears, preferably the gear 134, is of a diameter somewhat larger than the diameter of the gear 135, as shown more clearly in Fig. 23. The gear 134 meshes directly with the gear 137, which is secured to a shaft 138 forming a continuation of the drum or cylinder 127, and which projects beyond the support 1529. The gear 137 is loosely mounted upon the shaft 138 and the gear 139 is also loosely mounted upon the shaft 138. One of these gears, preferably the gear 139 is of a diameter somewhat smaller than the diameter of the, gear 137, and has connection with the gear 135 through the mediuniof an intermediate or idle gear 140 journaled to the These gears 137, 139 are respectively provided with clutch faces 141, 142, and a` clutch member 143 is keyed upon the shaft 138 intermediate the clutch members 141, 142, and is adapted to be moved into or out of engagement with either of .the clutch faces 141` 142 by means of an oper-il atingr Vhandle or lever 1444 (see Figs. 17 and 23) for locking the respectivegca'rs 137, 139 for. rotation .with the shaft 133, thereby controlling the direction of rotation of the drum 127 to canse the shaft 50, and consequently' the shaft 51 to rotate either forwardly or backwardly to imparta corresponding movement to the number bearing members of the totalizers, according to the work to be performed, that'is, according to whether the number to be registered on the totalizers is to be added to or subtracted from the amount already registered.

The drum or cylinder 127 is adapted to be intermittently rotated, and is also adapted for variable movement according to the number which it is desired to register on the totalizcrs. In order to control the degree of rotation of-the drum, selective mechanisms are` provided which are controlled by a series of keys 145, as shown more clearly in Figs. 1 and 3. The selective mechanisms which are controlled by these keys 145 and which in turn control the degree of rotation of the shaft 131, as well as the drum 127, will now. be describ'cd. These selective nleclianisms are similar in construction to the selective mechanisnis already described, which are 4adapted to render any one or more of the totalizer operating mechanisms active.

Secured to and for rotation with the shaft 131 a re a series of gears 116 which are spaced from each other longitudinally with respect to the shaft 1.31, and nine of these gears are provided, one for each of the keys 145, as shown more clearly in Figs. 3,1() and 1l. A shaft 147 is journaled in the Supports 132, 133. and is arranged preferably in the rear o1' the shaft 131 and parallel therewith. This .shaft 147 is spaced from the shaft 131 and mounted thereon are sleeves 148 which sleeves are secured to the shaft 147 for rotation therewith and are adjustable on the shaft longitudinally with respect thereto. These sleeves 118 are similar in construction to the sleeves 58, and are provided with a plurality ofcircumfercntial ribs 119 similar to the ribs 59. One of these sleeves 148 is provided for each of the gears 146, and supported by these sleeves for adjustment therewith are mutilated gears 150 so arranged that. when the sleeves are. adjusted in one direction on the shaft 147, the mutilated gears 15() thereon will mesh with the respective. gears 146. These gears 150 are provided with a dill'erent number of teeth ranging from 1 to 9, that is, the gear which i is connected with the sleeve 148 nearest the left hand side of the machine in the present exemplif'lcation of the invention, is *provided` with teeth corresponding to one unit,` aiid the` number of teeth on the gears' 15() progressively increase toward the gear ou the right hand side, and which latter 4e'a'a has an effective periphery nine times that'of the unit gear so' that when any one of the gears 150 is in position to |nesh \\'ith therespec tive gears 146, the shaft 131 will be given a ninnber of steps of rotation equivalent to thenulnber of teeth on the, mutilated gear 15G-"which is in an operative position. After the mutilated gear'has vimparted a corresponding number of steps of rotation to the shaft, 131, the mutilated gear will` be autopermit the 'carriage 46 and the gears 56 and locking elements 62 to be advanced, in. a manner as has already been set forth,

Any suitable means may be provided for shifting the sleeves 148 and the gears 150 ou the shaft, and for this purpose there may be provided a plurality of upright stems 151 which are adapted to be reciprocated y and are mounted for movement through a support 152 (see Figs. 8, 10, 11, 13, 16 and 21). These st`cn1s-151 pass loosely through the sleeves 153which are similar in construction to the sleeves 75, and which are:

mounted for axial movement in the supportv 152. These sleeves 153 are provided with segments 154 similar to the segments 78 of the sleeves 75, and the segments 154 mesh with the respective ribs 149 on the sleeves 148, so that when the Asleeves 153 are rotated in one direction about the stems 151, the sleeves 148 and associated gears 150-will be moved'A onthe shaft 147 longitudinally thereof, and in the corresponding direction, and when the sleeves 153 are-rotated in the opposite direct-ion, the sleeves 148 will be correspond.- ingly adjusted.

Each of thesleeves 153 is provided with a laterally projecting finger 155, and a spring 156 is secured by one extremity to each of the fingers 155, and is anchored by its other extremity to`a fixed support 157.

The support 157 and spring 156 are so arrangedV that thenormal tendency. of the spring 'is to rotate the sleeve` 153 in one directionv to correspondinglyV shift the sleeve 148. Each of the sleeves is also' provided with aA lateral projecting pin 15,8, and these pins 158 are adapted to be engaged by an arm, 159 secured to a rock'shaft 160, so that when the shaft 160 is rocked in a manner to be hereinafter set forth, the arms 159 will engage the projection 158 on the respective sleeves 153 to rotate the sleeves in the opposite direction and against the tension of the spring member 156 so as to shift the sleeve 148 on the shaft 147 in the opposite direction.

In order to lock the sleeves 153 against operation by the tension ofnthe spring 156 and to hold the gears 150 .out of mesh with the respective gears 146, suitable locking mechanism is provided, which, in the present exempliication of the invention, comprises' a notch .161 in the Sleeve 153, Within which a pin or projection 162 supported by the stem 151 is-adapted to be seated when the gears 150 are in inoperative positions. As soon as the stem 151' is shifted to unseat the pin or projectidu 162 from the notch 161, the

'spring 156 of the sleeve 153 which has 4been released will operate to-rotate the latter Any suitable means-may be provided for connecting the stems 151 .with the respective keys 145, so that when the latter are actuated, tle

- respective stems will be shifted to release or.

unlock thesleeves 153. For this purpose there is provided a plurality of arms 163 which are pivotally mounted intermediate their ends on a suitable support 164,.prefer -ably in the form of a bar or rod which is arranged to extend across the .machine and at a point above the shafts 131, 147 (see Figs. 3 and 8). The arms'163 are pivotally connected adjacent one end, as at 165, with the respective stems 151 and serve as' a means for supporting the stems. ,The other extremities of the arms 163 are pivotally connected as at 166 to the respective stems 167 of the keys 145, and these stems 167 pass loosely through the support 81. The arms 163 are preferably connected to the respective stems 167 of th'e keys 145 in such a manner that when the keys are depressed, the stems 151 will be elevated, and when the keys are returned to their normal positions, the stems 151 will be lowered so that the pins or projections 162 thereon will be seated in i ports 132, as shown more clearly in Figs.

1 and The shaft 147 is adapted to make one complete revolution andthen stop, and in order to impart this intermittent. rotation to the shaft, any mechanism suitable for this purpose may be employed. A suitable and etli cient means, however, will now be described and comprises a spring motor 170, the -nxle 171 of which is journaled (see Figs. 1, 14, 26' and 21) in any suitable support, I )referably` the support 132, and the motor is provided with peripheral teeth 172.` and the teeth are so arranged as 'to mesh with alpinion 173 on the shaft 147, asshown more clearly in Figs. 1 andV 10. This spring motor is provided. as shown in Fig. 21 with a plurality of lateral projectious174, 175, arranged in two series around the circumference of the casing, and coperating with these projections is an es- -ca ement com risinuF arms 176 177. and the the notches 161 of the respective sleeves 153.
